Toothpick Puzzles

Move four toothpicks, plus the small stone that represents the eye, and you can make this fish swim the other direction. That's easy. Now accomplish the same thing, but by moving only three toothpicks and the stone.

Puzzles like this aren't merely fun; they also teach new ways of thinking. James has selected some long-time favorite puzzles from other sources, and added his own, to create this collection.
